Orange-Sepia-ish Scans

[byron_fry1]

Hey guys, I am running into some problems with some of my negatives. I notice on certain rolls that one

or two of the negatives will be washed out and have a really orange tinge to it. This goes away if I scan in

greyscale. I am shooting tri_x, and the weirdest thing is that often these problem negatives seem to be an

isolated case, while there neighbours scan perfectly fine. As well, compared outside the scanner, there is

no visible difference between orange problem negs and good bw ones.

Anyone have this problem or know what I can try?

Scan in grey scale or convert to greyscale in your image editor. I don't know why it only happens on some. I often scan in color when I am using a staining developer. When I switch from color positive to color neg, the magenta positive changes to a green negative and I can estimate the strength and distribution of the stain.

If you generally output the scan data in color, I wouldn't switch to greyscale for these cases. Just deal with it in post process. It's debatable, but I've always found I get richer scans of black and white film by initially ouputting all 3 scanned color channels.
